A highly modular method for the synthesis of (Z)-3-[amino(phenyl/methyl)methylidene]-1,3-dihydro-2H-indol-2-ones starting from easily available 3-bromooxindoles or (2-oxoindolin-3-yl)triflate and thioacetamides or thiobenzamides is described. A series of 49 compounds, several of which have previously been shown to possess significant tyrosin kinase inhibiting activity, was prepared in yields varying mostly from 70 to 97% and always surpassing those obtained by other published methods. The method includes an Eschenmoser coupling reaction, which is very feasible (even without using a thiophile except tertiary amides) and scalable. The (Z)-configuration of all products was confirmed by NMR techniques.

Eschenmoser偶联反应合成（Z）-3- [氨基（苯基）亚甲基] -1,3-二氢-2H-吲哚-2-酮

一种高度模块化的方法，从易于获得的3-溴代吲哚或（2-氧代吲哚开始）合成（Z）-3- [氨基（苯基/甲基）亚甲基] -1,3-二氢-2 H-吲哚-2-酮描述了-3-基）三氟甲磺酸盐和硫代乙酰胺或硫代苯甲酰胺。制备了49种化合物，其中一些化合物先前已显示出具有显着的酪氨酸激酶抑制活性，其收率大多在70％至97％之间变化，并且始终超过通过其他已公开方法获得的产率。该方法包括Eschenmoser偶联反应，该反应是非常可行的（即使不使用除叔酰胺以外的亲硫基团）并且可扩展。所有产物的（Z）-构型通过NMR技术证实。
